Title: Plasma treatment power source
Inventor: WATANABE ETSURO
IPC: H01L21/302
Filed: 1984-09-17
Abstract: PURPOSE:To enable the discharge power desired at a discharge power set value to be controlled stably with good reproducibility by providing a variable gain amplifier which can linearly vary the discharge voltage to the discharge power set value. CONSTITUTION:It is assumed that a discharge power set value such as A is given from a discharge power setting circuit 1 to a buffer 2. Then, the buffer 2 passes a current proportional to an input voltage (discharge power set value A) into the LED3a of a gain controller 3. This makes the variation in resistance value of a variable resistor 3b; however, the relation between the current flowing through the LED3a and the varying resistance value is linear without effects of the ambient temperature and the like, and so the gain of an amplifier 4 is made variable in linear form. Therefore, the relation of the output voltage Vo the input voltage Vin of the amplifier 4 is as shown by Fig. 1, and the discharge power set value A becomes proportional to the output voltage Vo.

Title: Stepping motor control system
Inventor: OKABE NORITOSHI
IPC: H02P8/22
Filed: 1988-08-03
Abstract: PURPOSE:To allow a stepping motor to perform high resolutive driving in a low speed region without reducing the speed in high speed driving by switching over exciting pattern data in accordance with the driving frequency of the motor. CONSTITUTION:In a region not more than 500pps of driving pulses the 16-split high resolutive driving by the microstep control is performed as a high-order address of a ROM 3 is selected. In a region not less than 500pps of the driving pulses a low-order address of the ROM 3 is selected and the high speed driving is allowed as the exciting pattern data is switched over to a normal single phase exciting pattern, a mono-to-two-phase exciting one and a two-phase exciting one. On that account, high resolution and low oscillation can be materialized without sacrificing the high speed.

Title: Method for measuring crystal face azimuth of silicon wafer
Inventor: MORIKAWA HISASHI
IPC: G01B21/08
Filed: 1985-08-31
Abstract: PURPOSE:To identify not only the azimuth of a crystal face but also the thick ness of a wafer, by forming a square-shaped etching pattern with an anisotropic etching solution. CONSTITUTION:A film removing part 3 is formed on the back surface of a silicon wafer 1 having films 2 covering both surfaces thereof and anisotropic etching is performed with an alkaline etching solution. Silicon is gradually etched from the film removing part 3 on the back surface of the wafer 1 to form a square-shaped pattern comprising a quadrangular pyramid shaped recessed part. When etching advanced to a certain degree, the etching surface becomes flat gradually. This surface coincides with a crystallographic face (111) of a low index. If it is assumed that the face of the wafer is (100), four azimuths can be identified by four sides of the square-shaped etching pattern. When (x) is the length of the side of the pattern on the back surface and (y) is the length of the side of the pattern on the front surface, the thickness (t) of the wafer can be calculated according to the equation.

Title: Fuel supply control device for internal combustion engine
Inventor: TOMIZAWA NAOMI
IPC: F02D45/00
Filed: 1990-07-23
Abstract: PURPOSE:To suppress abnormal increase of a combustion temperature and avoid wasteful decrease correction by providing a decrease correction means based on a generated quantity of heat for comparing a parameter related to a generated quantity of heat computed through a generated quantity of heat computing means to a specified value and correcting a decrease correction rate of a fuel supply amount supplied through a high load time fuel decrease correction means. CONSTITUTION:A parameter related to a generated quantity of heat is computed by a computing means based on an inner-cylinder pressure during combustion. According to the operation condition at this time, a fuel increase correction rate under a high load is decreased by means of a correction means within a range where a combustion temperature is not abnormally increased. As a result, a fuel consumption ratio and exhaust ability are improved under a high load without decreasing correction which sets the air-fuel ratio to be an over-rich condition wastefully. A memory means memorizes corrected fuel increase correction rates according to the operation conditions while monitoring the generated quantity of heat. Unsatisfactory responsiveness, that is, correcting gradually from an excessive or insufficient initially set correction rate to an optimum value, is avoided.

Title: Sheet feeding device
Inventor: NAKAMURA KIYOSHI
IPC: B65H3/08
Filed: 1990-07-20
Abstract: PURPOSE:To increase the reliability of a sheet ordering process and eliminate production of scratches in the surface of a sheet by providing a sheet sucking means and a sheet ordering means of which sucking position and applied position are freely changeable corresponding to the size of the width of the sheet. CONSTITUTION:For sucking means 21a - 21c and a sheet ordering means 50, their sheet sucking position and sheet applied position are changed corresponding to the width size of a sheet 20 to be fed. If the size of the sheet 20 to be fed is changed, therefore, the position relation of the sheet sucking position to the sheet applied position is kept constant. The degree of bend of the sheet 20 of which both ends are applied to the sheet ordering member 50 is therefore constant regardless if the sheet size is large or small. The position relation is set to such a degree that the bend degree of the sheet end parts enables a secure ordering process and that scratches are not produced in the surface of the sheet.

Title: Drilling spear for drilling device for fuel tank
Inventor: MIYASAKA KIYOTO
IPC: B67B7/46
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent the part around a hole drilled on the bottom of a fuel tank from being kept as it is recessed upward and smoothly discharge the fuel completely, even when the hole is bored from the underside in a steel fuel tank of a scrapped vehicle. SOLUTION: A cutter 14 is formed at the front end of a spear body 13 having a cone-shaped section. A level difference is provided at the lower end of the cutter 14 to form a hooking part 15. The drilling spear 12 is stuck from the lower side to the upper side until the hooking part 15 pierces through the bottom plate of the fuel tank. In this time, the bent piece cut by the cutter 14 and turned up at the periphery of the hole springs back and enters the underside of the hooking part 15. When the spear is pulled down in this state, as the bent piece is caught by the hooking part 15, a downward force acts on the bottom plate around the hole and hence, a recess turning up in the bottom plate of the tank can be eliminated.
